Percussion drilling set - hammer Cobra TT, RD32

04.19.SC

The percussion drilling set for heterogeneous soils with RD32 and a gasoline powered percussion hammer (Cobra TT) is standard equipped for drilling to a depth up to 16.4 feet (5 meter).

  • Equipped for drilling to a depth up to 16.4 feet (5 meter)
  • With gasoline powered percussion hammer (Cobra TT)
  • The solution for city centers/industrial sites
  • Beautiful clean samples, no lubricants used
  • Can be combined with liner or foil sampling

Description

The percussion drilling set is perfect for soils with bricks, large or many stones, for example in urban areas or industrial sites. With this drilling set you get beautiful clean samples without the use of lubricants. The set is equipped with extremely robust rods and gouges. The different diameters allow efficient, fast, and light work. Please note that this set does not replace cutting with a diamond core and is not intended for fibrous material. Do not use the set on dry glacial loam, porosity is required.

RD32-connection
The percussion drilling sets are equipped with RD32-connection extension rods and percussion gouges are screwed together using a coupling sleeve. The RD32-connection is used in firmer, dryer soils. The RD32-connection takes very little time to attach and take off. The RD32-rods connect together by means of a coupling sleeve, which means that the massive extension rods have the same diameter along the entire length, which makes them very strong.

Applications

  • Soil profile description and classification
  • Soil sampling above and below groundwater table
  • Environmental soil research
  • Undisturbed sampling

Set contains

  • Gasoline driven percussion hammer with accessories and wooden transport box
  • Various extension rods
  • Coupling sleeves
  • Percussion gouges (combination type for various types of soil) in various diameters and lengths
  • Core sampler for PVC sample tubes and foil liners
  • Mechanical rod puller

* Please check that the stones and/or bricks do not exceed the diameter of the percussion gouges too much. If the stones can be pushed aside by the cutting shoe, or they can enter the gouge, there's no problem. Too large stones, or bricks that can not move, shall block the drilling and most likely break or damage the cutting shoe on the percussion shoe. However, cutting shoes can easily be replaced.
